Can not be generally used in this context, because they have a different spectral sensitivity than solar cells on the market and therefore possibly more or less inaccurate conversion formulas to the solar cells actually processed parts of the Lead total radiation. It is therefore common practice to determine the solar irradiance with the help of solar cells with those of the respective PV generator are technologically similar. The problem is, however, the required calibration of the radiation sensors used, since even minor measurement errors can lead to significant deviations in the assessment of the performance of a PV system.
  • a disadvantage of the last-mentioned procedure is that despite the use of similar technologies, different measurement results for the irradiance are achieved. This is z. B. a consequence that different production times or production sites, other embedding methods, quality variations of the materials used od. Like. Can lead to different properties of otherwise similar solar cells and therefore the behavior of the measuring solar cells when irradiated other than the behavior of the solar cells of the PV generator can be at the same irradiation.
  • the technical problem of the present invention is to design the method and the device of the generic types described above so that an even more accurate determination of the irradiance is possible and measurement errors due to the described possible differences in the solar cell properties are almost completely avoided.
  • the invention has the advantage that a solar cell of the finished PV generator is used as the measuring solar cell. Since it can be assumed that the solar cell of a PV generator selected as the measuring cell with respect to material composition, embedding, spectral sensitivity, reflection behavior, etc., is identical to all other solar cells of the same PV generator, the measured values determined with such a measuring solar cell lead to irradiation intensities , which largely corresponds to the irradiances to which the entire PV generator is subjected To be in harmony. In addition, there is the advantage that in order to generate the energy required for the measuring arrangement, the entire PV generator and not just a single measuring solar cell is available as before.

Such a calibration can be done with a flash lamp (flash method), with a continuously operated lamp (simulation method) or under natural sunlight (out-door calibration). The known fact is exploited that produced by the same technology, for.

  • the ratio of the fed into a network electrical power of the PV generator 1 to the measured solar radiation power (performance ratio) can therefore be determined more accurately than before, with the result that can be checked very accurately whether the output from the PV generator 1 electrical power is compatible with the irradiated solar power or somewhere there is a fault.
